Equipoise zero gravity arm

Currently all exoskeleton prototypes for holding heavy tools in an industrial setting share a similar design. Originally, Ekso Bionics and Lockheed Martin collaborated on the HULC a hydraulically powered exoskeleton for the military. The project was a failure, but a stripped down HULC frame was used to create a passive exoskeleton that could support a heavy industrial tool using the zeroG™ arm. At the time, Ekso Bionics reported that while they are interested, the company does not have the cash to invest in this application. Lockheed Martin then took this early prototype and contracted Robrady Design to make what ultimately became the FORTIS passive exoskeleton for industrial use. For more on this, see Daily Tech’s From HULC to FORTIS: the Evolution of Lockheed Martin’s Incredible Exosuit .

"Mathematics is not a careful march down a well-cleared highway, but a journey into a strange wilderness, where the explorers often get lost. Rigour should be a signal to the historian that the maps have been made, and the real explorers have gone elsewhere." ~Anglin, . "Mathematics and History", Mathematical Intelligencer, v. 4, no. 4.
